snaasn-msrnnsme DEVICE.

To all whom it mag concern:

Be it known that I, James H. MONTGOM- nRY, a citizen of the United States,'--residing at Butte, in the county of Silverbow, State of Montana, have invented certain new and useful Improvements in Grease-Dispensing Devices, of which the following is a descripreference beinghad to the accompanytion,

ing drawing and to the figures of reference.

marked thereon.

The invention relates to new and useful improvements in grease dispensing devices and more particularly to a device whereby grease received in commercial receptacles or barrels may "be dispensed directly from the receptacle or barrel in which it is received.

An object of the grease dispensing device of the above, character which is so constructed thatthe entire contents of the receptacle or barrel may be dispensed through said dispensing device.

A further object of the invention is to provide a device of the above character having a dispensing pump and an intermediate receptacle which is adapted. to receive the barrel or receptacle in which the grease is shipped in inverted position so that the grease may be fed by its own weight into this intermediate receptacleand from the intermediate receptacle to the pump.

A' still further object of the invention is to provide a grease dispensing device having a pump anda reciprocating piston for spensing the grease with a vent opening for the pump which the air to escape from the um'pi so grease may enter the same y gravity.

' These and other objectswill in part be obvious and will in part be hereinafter more fully disclosed.

In the drawings which. show by way of illustration one embodiment ofthe inventi0n:- 1

- The grease dispensing device consists of a support mounted on suitable rollers andembodied in this supporting device is a pump having means 'for forcibly expelling the contents of the receptacle. This pump may be in the form of a reciprocating piston pump or in the form of a screw pump. The support also carries a receptacle whichreceives,

section onto which the receptacle or barrel is Y inverted after the entire end has been taken out of the barrel so that the grease in the barrel will pass by gravity down into the J intermediatev receptacle and thence into the invention is to provide a In a reciprocating pump when the brought backair is liable to accumulate in front of the piston and prevent the grease from passing by gravity into the pump. In order to permit the free flow'of the grease into the'pum'p I have provided said pump with a. vent hole which 'is unpump.

covered when the piston is withdrawn so that any air in advance of the piston may be ,forced out of the pump b the grease as it is forced by its own weig t-into the pump.

This vent hole is, of course, closed when the piston moves forward to' expel the grease in the pump.

Referring morein detail to the drawings my improved grease dispensing. device con sists of a support 1 which is mounted on wheels 22 and a roller 3 attached to a Patented Apr.27, 1920. Application filed September 29, 1916. Serial No. 122,862.

bracket at the forward end of the support. 1 These wheels and the roller facilitate the v movement of the dispensing apparatus from one pointto another. Formed as a part of the support or extending; upwardly therefrom is a receptacle 4. tapered side walls 5 and 6 which are joined to the pump casing 7. at their lower edges.

Said rece tacle 4 also has a rear tapered he side walls of the receptacle 4 wall ,8. are substantially vertical at the upper part of the receptacle thus forming a wide open mouth. The grease is shipped inreceptacles or barrels, one of which is indicated at .B in the drawin s. This receptacle or bar rel is provide with a suitable bottom 9 his receptacle has as to engage the barrel orreceptacle B.

The pump casing 7 is provided with an inner section 12 in which a piston 13 is rethe atmosphere. The inner casing 12 has ciprocated by means of a piston rod 14. The piston rod 14 slides in a bracket 15 and is moved back andv forth by a hand lever 16 which in turn is pivoted to a bracket 17 detachably connected to the grease dis ensing device. This inner section 12 exten s from end to end of the pump and is provided with .an opening 18 which is adapted to register with an opening 19 in the-.side wall of the pump, when said inner section is in the position shown in Figs. 1 and 2 of the drawings. The piston rod 14 has a spiral groove 20 formed therein. The inner section 12 carries a lug which engages the groove 20 so that when the piston rod is moved forward it will rotate the inner section 12, thus closing the opening 19.

The pump casing is formed with an opening 21 connected with a pipe 22 leading to an opening 23 which registers with the opening. 21 when the parts are in the position shown in Fig. 1 (see Fig. 3). The pump casing 7 has a delivering nozzle 24 to which a flexible pipe 25 may be attached. In the operation of my device the grease is received in commercial barrels or receptacles made for the purpose. The upper end of the barrel is removed and the grease dlspenslng deviceis inverted and attached to the open end of the barrel by slipping the vertical portion of .the intermediate receptacle over the top of the barrel or receptacle. These parts are then connected by the vertical strip 10 after which the whole device with the barrel is turned over to the position shown in Fig. 1. This allows the entire contents of the barrel to slide down into the intermediate receptacle 4 and fill the same. The pump is usually left with the piston 13 forward and this closes the opening in the side wall of the pump chamber. The operator withdraws the piston which turns the inner casing and opens the pump chamber to the intermediate receptacle 4. The pump chamber is also opened to the atmosphere. The grease in the'intermediate chamber flows b gravity down mto the pump chamber. en the piston 1s moved forward the grease in the pump chamber will beforced out through the delivering nozzle and the flexible pipe 25. I

From the above description it will be apparent that the grease will flow from the barrel or receptacle 'in which it is shipped into the intermediate receptacle and thence into the pump and finally the barrel or re ceptacle in which the grease is shipped will be emptied. When the barrel is emptied it will be removed and another barrel inverted on the dispensing device in the manner above described. By my improved dispensing device the entire contents of the barrel may be emptied. In order that the sides of the barrel may be scraped I have provided a follower 26 which is secured to the bottom of the barrel by small bolts 27 After the contents of the barrel have been completely dispensed these bolts may be released and the follower 26 will drop of its own weight thus scraping the sides of the barrel. It is obvious that the barrel may be provided with a suitable vent openin if desired.

n the construction shown in" Fig. 1 the pump casing is of a predetermined size and therefore the amount of grease dispensed may bedetermined by the number of reciprocations of the piston;

walls at its upper end and tapering side' walls at its lower end, a horizontal station'- ary c lindrical member communicating with t e opening between the lower' ends of the tapering walls, a rotary :cylihder within the stationary cylinder and having an opening corresponding with the opening in the stationary cylinder, a piston in the rotary cylinder, a piston rod, means carried by the piston rod for rotating the cylinder for preventing grease from entering the.

cylinder in rear of the piston on the forward movement of the piston.

2. In an apparatus of the character described, the combination with a receptacle including a support secured to the receptacle, a cylinder carried by the support-and in communication with; the receptacle, a piston for forcing the grease from the cylinder, means operated by the forward movement of the piston for closing the communication between the cylinder and the re ceptacle during the time the piston is forcing the grease from the c lmder.

3. In an apparatus of t e character described, the combination of a receptacle provided with a mouth portion adapted to receive and hold thereon in inverted position a receptacle containing grease in bulk,

- said receptacle having tapering sides, a means controlling the movement of said cylindrical casing having an opening arsleeve valve. 10
